To all whomy it may concer/a.'

Be it known that l, ALLEN EDWARD OsTRANDEn, residing at the city, county, and State of New York, and being a citizen of the United States, have invented certain new and useful Improvements in Car-Underframes, of which the following is a full, clear, and exact description, suoli as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which illustrate the preferred form of invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

This invention relates to improvements in underframes for railway cars, and is especially adapted for use in cars having side, center and end sills of wood, or other material suported in a given plane, with holsters, cross- A earers and draft sills in another plane, while said draft sills are suitably connected so as to transmit huffing and pulling stresses without undue strain on the floor-frame used as a support for the load. To that end l have produced the structure disclosed in the accompanying drawings in which the longitudinal sills extend from end sill to end sill, there being continuous holsters and con tinuous cross-bearers suitably disposed below said longitudinal sills, and end sills in the same plane with the longitudinal sills, there heing also truss rods extending from end sill to end sill, as shown, and struts cooperating with the said truss rods. Positioned hetween the said cross-bearers and some of the said struts is a continuous draft-transmitting connecting member' in the form of a channel which is horizontally disposed, that is with the flanges thereof depending helm-f.'V the weh of said connecting member, while short draft sills extend from the holsters relatively flush with the outer face of the usual dead-block and hy said draft-sills is carriei'l the draftrigging. The inner ends of the draft sills are connected to the holsters and to said draft transmitting member by suitable rigid connections independent of the center sills so that pulling stresses will he received and transmitted by said draft-sills and connecting member, while cross-bearers extend preferably from side sill to side sill, or to the equivalent of said side sills, and serve to distribute the load carried by said car. Said cross-bearers serve also as a means for holding the draft transmitting member in proper position and serve as means to resist tendency of said member to buckle during buffing of the car.

In the drawings referred to, Figure 1 is a plan view embodying the elements of my invention. Fig. 2 is a longitudinal section taken on line 2 2 of Fig. l. Fig. 3 is a transverse section taken on line 3-3 of Fig. 1. Fig. 4 is a transverse section taken on the line 4wd of Fig. 1. Fig. 5 is the end elevation. Fig. 6 is a fragmentary view of the side sill showing method of stiffening the ends of holster. Fig. 7 is a view similar to Fig. 6 showing method of stiffening end of the cross bearer or needle beam. Fig. S is a fragmentary section taken on the line 8-8 of Fig. 1. Fig. 9 is a fragmentary section taken on the line 9)-9 of Fig. 1. Fig. 1() shows details of box connection for draft sills and holsters.

Referring to the drawing 1 indicates the usual wood end sill of the car, which is secured to the center sills 2 side sills 3, and intermediate sills 4 of the car, all in accordance with the usual accepted standard practice. Below the sills l use a holster which is composed of two I-beanis 5, each heilig continuous from side sill to side sill. The cross bearer or needle beam 6 is a steel member preferably of an I-section, which also is in one continuous lenO-th from side sill to side sill. Below the boilster and cross bearer I place a longitudinally extending channel 7, which is secured to the above mentioned members, and at the bolster and cross bearers l have interposed Ousset plates 8, and 8 respectively, which a lows for more rivets being used to secure the parts together.

The main stiffening member or back bone 7 of the under-frame is prevented from buclding at points intermediate the cross bearers and holsters by braces 9. These braces are riveted to the steel member 7 and bolted to the wooden sills. Truss rod supports are secured at the cross bearers, the outside supports 10 being secured to the bottom flanges of the cross bearers 6 by rivets 10 and the center truss rod support 11 is arranged to seat in the channel 7, to which it is secured by rivets 11 1. At the ends of the hack bone 7 the draft sills 12, preferably of channel section, are secured by means of gusset plates 13 placed one on either side of the channel .7 and securedV thereto -by rivets 14 passing through the gusset plates and flanges of the channel, rivets 15 passing through the gusset plates and web of the draft sills. upper edge of the draft sills is secured a box shaped pressing 16 shown at a larger scale in Fig. 10. The upper flange 17 of this box pressing is secured by rivets 17 a to the top cover plate 18 of the bolster, and is also secured to the top ange of the contiguous -beam forming part of said bolster. The down turned flange 19 of the pressing is secured to the webs of the contiguous llbeam 5 of the bolster and is deeper to give more space for rivets than are the side flanges 2() which are secured to the draft sills. rlhe usual stops 21 for the draft rigging are riveted to the draft sills as shown, and the draft sills are secured at their oute-r end by coupler carrier irons 22, which are fastened to the deadwood 23, all as per usual construction. Center truss rods 24, as applied, pass through the deadwood 23 and over the truss rod saddles 25 which are secured to the top of the bolster. As shown in Fig. 8 this saddle 25 is made 'with lips 26 extending over the edges of the bolster, the object of which will be hereinafter explained. At the needle beams center truss rods fit into the brackets of the strut 11 and are held in place by pins 27 driven through the ends of these brackets. Side truss rods are applied in a similar manner, said side truss rods extending through the end sills, over side truss rod saddles 25a and under the outside supports or queen posts in which the rods are held by pins 27 as before described and as will be readily understood by reference to the drawings.

lhe center line of the coupler, which will be the center of bufling and draftV rigging is somewhat above the center of resistance represented by the back bone 7 which would result in a tendency to tip the bolster members 5 sidewise. l overcome this tendency by forming lips 26 on the truss rod saddles mentioned heretofore, which, when the truss rods are pulled up tight, serve to hold the bolster in an upright position. The bolster is further stiffened by means of straps or braces 28 located at the ends'of the bolster as shown in 1Eig. 6, which straps are riveted to the bottom flange of the members 5 and are secured to the wooden sills by bolts 29. A similar method is employed for stiffening up the ends of the needle beams 6, a strap 30 being secured to the bottom flange of the beams and bolted to the side sills.

Should the construction of the car be such that a bolster of greater or less depth than that shown in the drawings is required, it is obvious that this change could easily be made without affecting the depth of the Near the draft sills it simply requiring a deepening or increasing in width of the gusset plate 13.

Var ons other modifications of my invention will readily su st themselves to one skilled in the art, and it should be distinctly understood that l do not limit myself to the exact construction as shown in the drawings.
